DNMG150608-FM5 WMP20S — Turning indexable insert, Tiger‑tec Silver, for rostfreier Stahl (Walter Tools)

DNMG150608-FM5 WMP20S is a negative‑rake turning insert engineered for reliable stainless‑steel machining in medium to robust conditions

• Tiger‑tec Silver coated grade WMP20S
• FM5 chipbreaker for controlled chips
• Negative rake 0° for stable cutting forces
• Rhombic 55° form with 0.8 mm corner radius

Stable cutting in rostfreier Stahl for uninterrupted production

The combination of the Tiger‑tec Silver coating and the WMP20S grade provides improved thermal resistance and wear control when machining rostfreier Stahl, materials known for work hardening and high heat generation. The coated carbide substrate promotes a reliable cutting edge under medium to robust conditions, which translates into fewer interruptions and a steadier process flow. The FM5 chipbreaker supports predictable chip formation, reducing the risk of built‑up edge and improving cycle stability.

Predictable edge life through geometry and edge preparation

The insert’s rhombic 55° geometry and negative rake 0° are selected to deliver consistent cutting forces and a robust cutting edge in demanding turning operations. The 0.8 mm corner radius moderates stress concentration at the cutting edge, extending tool life on interrupted cuts and when facing variations in material hardness. These geometric choices favour repeatable results and reduce the need for frequent tool changes, improving shopfloor productivity.

Practical benefits of the FM5 chipbreaker in production

A well‑matched chipbreaker such as FM5 controls chip flow and cross‑section, which is particularly important for long turning passes and deep cuts in rostfreier Stahl. Controlled chips help protect the workpiece surface finish and reduce handling time. In practice, this means fewer secondary operations for chip control and lower risk of surface defects, supporting a faster throughput with maintained quality.

Application guidance and process reliability

This insert is intended for general turning tasks where a coated carbide grade for rostfreier Stahl is required. Its design delivers process security and consistent edge performance, making it suitable for batch production as well as single‑part runs with variable cut conditions. For specific feeds, speeds and toolholder matching, Metav Werkzeuge’s consultants can provide tailored recommendations based on the component geometry and machine capability.

FAQ

Is this insert suitable for machining stainless steel?
Yes. The DNMG150608-FM5 WMP20S insert features the Tiger‑tec Silver coating and a WMP20S grade formulated specifically for machining rostfreier Stahl under medium to robust conditions.

What benefit does the FM5 chipbreaker provide?
The FM5 chipbreaker on this Walter Tools insert promotes controlled chip formation, improving surface quality and reducing the likelihood of built‑up edge when turning rostfreier Stahl.

Can the insert be used with standard toolholders for DNMG inserts?
The insert follows the DNMG designation and is compatible with toolholders designed for DNMG‑type inserts; correct toolholder selection and clamping are recommended to realise the described performance.

What does the 0° negative rake mean for cutting behaviour?
A negative rake of 0° increases edge strength and stabilises cutting forces, favouring robust machining and longer tool life in demanding turning operations.
